Estimate the area of the circle using 22/7

Step-by-step explanation:

You can observe in the figure that the value of the diameter of the circle is

Then, since you know the diameter , you can use this formula for calculate the area of the circle:

Where "d" is the diameter.

Then, substituting   and   into the formula, you can estimate the area of the circle. This is:

answer is 67%
